Discussion on calculation method of detection limit and quantitative limit of occupational health biological monitoring method / 中华劳动卫生职业病杂志

ABSTRACT

Objective@#To discuss calculation method of detection limit and quantitative limit of occupational health biological monitoring.@*Methods@#The detection limit and the quantitative limit of phenyl glyoxylic acid and Mandelic acid were calculated by using three different methods of IUPAC, NIOSH and OSHA respectively.@*Results@#The IUPAC, NIOSH and OSHA methods were used to calculate the detection limit and the quantitative limit of the phenyl glyoxylic acid and Mandelic acid, and the results are different.@*Conclusion@#To calculate the detection limit and quantitative limit of occupational health biological monitoring methods, the standard curve method is adopted to ensure that the rate of detection in the vicinity of detection limit and more than 75% of the quantitative limits are used.
